Dunlop Electric Bass Guitar Robert Trujillo Icon Series Taper Core 5-String (non-taper B), .045 - .130, RTT20054JackSeptember 13, 2009I strung these strings on my Ibanez SR 505. They were decent strings, and gave a nice bright sound. Didn't like them as much as D'Addario Pro-Steels, but still would highly recommend
